SIGNOR TO U. S. SLIGING MACHINE COMPANY, OF LA FORTE, INDIANA, A CORPO- RATION OF INDIANA SLIGING MACHINE Application filed January 20, 1926, Serial No. 82,405, and in Germany September 18, 1925. Renewed September 5, 1930.

The invention relates to a meat cutting machine and particularly refers to a machine of this kind having a rotary circular knife and a reciprocating table essentially for hand operation. As compared with known machines the new machine is substantially simple in construction and therefore considerably cheaper in the manufacture, for which reason it is primarily suitable for household purposes.

The machine, according to the invention is characterized in its main points by the fact that the table supporting the material to be cut moves parallel to or approximately parallel to the plane of rotation of the circular knife about a point located above.

The advantage obtained thereby over known machines of this kind must be seen in the feature that a very small force only is required for the return movement of the table subsequent to the severance of a slice from the material to be cut, so that a great saving in power as compared with other machines is to be noted.

The drawing shows an embodiment of the subject matter of this invention, and inthe drawing:

Fig. 1 is a front elevation; and

Fig. 2 is a side elevation of the meat cutting machine.

Fig. 3 is a section on line 33 of Fig. 2.

A standard 2 is secured on a base plate or foot plate 1 or is made integral respectively with said base plate. The shaft 3 for the rotary circular knife 4 is supported in the standard 2. The table 5 carrying the material to be cut is equipped with a carriage 6 and the customary holding or clamping device 7 for the material 26 to be out. A bar 9 is secured to the table 5, said bar carrying at its free end a ball 10. The ball 10 is supported in an arm 11 secured to the standard 2. An arm 12 is connected with the bar 9 in some suitable way, the free end of said arm being secured to a tape 13 of steel or some other suitable material. The other end of the tape 13 is fastened to a disc 14 which is constructed as a one-way clutch and which is mounted on the shaft 3 of the circular knife 4. The disc 14 is associated with a spring 15 which surrounds the 3 between the disc and the bearing, the other end of the spring being anchored in a suitable way' on a fixed part of the machine. A

handle 19 preferably of bail shaped form is secured to shaft 24 on one side of the table 5 and is rotatable with the shaft, said shaft carrying a lever 20 at that end which is opposite the knife. The rotation of the handle 19 and shaft 24 in a counter-clockwise direction, as viewed in Fig. 1, is limited by the engagement of the handle with the table 5 or a suitable stop thereon such as 31, shown in Fig. 3, so that the first effect of pressure on the handle is to effect a partial rotation of the shaft 24 to operate the ratchet feed mechanism, hereinafter described. Further pressure on the handle will move the table to the left past the knife. The movement of the handle in the opposite direction may be limited by the stop 32 on handle 19 abutting against the-stop 31 on the table or by any other suitable means. The arm 20 which is directed downward is connected by means of a link 21 with a double arm lever 22 carrying the ratchet pawl 23. The ratchet pawl cooperates with a ratchet 25 on a feed spindle 27, the spindle producing periodic movement of the carriage 6 by means of a feed nut 30, the carriage 6 supporting the material 26.

Two braces 16 are secured tothe table 5 near that end which is directed towards the knife4, the lower ends of said braces having rollers 28, 29 thereon, adopted to travel in a groove of a bar 17 which is secured by brackets 18 to the pedestal or base plate 1. The bar 17 has the shape of a circular arc and the center of this are coincides with the center of the ball 10. The operation of the machine is as follows: When the handle 19, Fig. 1, is moved from the position shown in Fig. 1 to the left, the table 5 with all of the parts secured thereto is turned towards the knife 4. This results in a swinging movement of the rod 9 by means of which movement is also imparted to arm 12 in such manner that the disc 14 is turned to enter into the clutch connection with the shaft 3, whereby the knife 4 is rotated to sever a slice from the material 26 to be cut. When,

then, a pull is exerted on the handle 19, the table 5 returns to its original position, the

tape 13 rewinding itself owing to the action of the spring 15 on the disc 14, whereby, however, the disc 142 does not cause rotation of the shaft 3 and the knife remains stationary while the ratchet pawl 23 slides on the teeth of the ratchet 25. Through the next succeeding pressure on the handle 19 the lever 20 is turned so that thru the connection of the link 21 the lever 22, the ratchetpawl 23 and the ratchet 25, the carriage 6 is advanced to the desired extent in such manner that the material 26 to be out again assumes a position in which upon the next swinging movement of the table 5 another slice is severed,
